This week's Torah portion is an exercise in math. First, we add up all adult males between 20 and 60, as part of the census. Then, we describe the division of the land of Israel amongst the tribes. Next, we contemplate a Jewish nation without Moses -- a most painful subtraction -- and the ascension of Joshua. Finally, the parsha ends with instructions on the multiplication of sacrifices offered on Shabbat, Rosh Chodesh and other festive days. This week's Shabbat menu involves recipes with 1 dish, 3 onions, 5 spices and 7 layers of chocolate. Now, that's my kind of math!
